2. Introduction
• Currently communication systems are based on either
electronics or photonics .
• However , for transporting huge amounts of data at a high
speed along with miniaturisation both these technologies are
facing limitations.
• So researchers are pioneering a new technology called
“PLASMONICS”.
3. What is Plasmonics?
• Plasmonics is the study of the interaction of light and metal
under precise circumstances.
• Plasmonics is thought to embody the strongest points of both
optical and electronic data transfer , allowing the fast
transmission of information over very small wires.
• The term „PLASMONICS‟ is derived from Plasmons.
4. PLASMONS
• Plasmons are density waves of electrons , created when light
hits the surface of metal under precise circumstances.
• These density waves are generated at optical frequencies , and
are very small and rapid.
• They can theoretically encode a lot of information , more than
what‟s possible for conventional electronics.
• Plasmons are the Nanostructured metals.
5. Need for Plasmonics
• Optical fibers now span the entire globe,guiding light signals
that convey voluminous streams of voice command vast
amount of data.
• Photonic devices
• Electronic circuits
• Photons & Electronics
• Mismatched capacities and sizes
6. • Researchers are can cobble them together ,but a single
technology that has the capacity of photonics and smallest of
electronics with the best bridge of all Researchers are
pioneering such technology called “ PLASMONICS”.
PLASMONICS breaks the fact :
The fact that light interacts with
nanostructures overcome the belief held for more than a
century that light waves couldn‟t interact with anything
smaller than their own wavelengths.
7. Communication with plasmonics
• Huge control over EM waves at Nano-scale.
• Surface Plasmons generated at the metal dielectric interface
cloud allow plasmons to travel along nano-scale wires.
• In order to fabricate effective plasmonic devices nanostructure
materials must be used.
8. Applications
• Graphene
• Plasmonic solar cells
• Plasmonic LED
• Plasmonsters - A faster chip Graphene structure
• Invisibility cloak - Let‟s fun with mr.india
• Plasmonic Therapy – Cure for cancer
• Quantum dot Plasmonics
• Plasmon printing.
10. Quantum dot plasmonics
• These are the semiconductor nano crystals .
• It couples strongly both photonics and electronic property.
• These are used for making superfast computers that can
transfer data up to 10Gbps .
• Used in optical applications such as imaging
11. Future directions
• To develop new optical components and systems that are of
same size as today smallest integrated chips.
• Plasmon sources , detectors , switches and wires as well as
splitters can be developed.
• Molecular switches
• All frequencies of the visible light must be covered
12. Challenges remaining
• The dream of making all-Plasmonic devices requires further
research .
• In order to realise advanced active circuits , there is a need for
active modulator and components operating at Ultra-high
bandwidth and low power utilisation.
13. Conclusion
• Plasmonics will drive us to a work of high speed
communication network , where we can convey voluminous
stream of voice and vast amount of data . Plasmonics is the
great boon of nano technology .
